如何在通知发送PendingIntent到服务后隐藏通知面板 [英] How to hide Notification Panel after sending a PendingIntent to Service in a notification

问题描述

所有

我写了一个服务来更新系统状态，我用startForeground把服务前台，还加入了通知吧。在通知中，我使用远程视窗有三个图像有三个OnClickPendingIntent。其中一人被发回给服务，并执行通知更新codeS。

code创建通知：

 意图int​​entApp =新的意图（这一点，ScreenOffWidgetConfigure.class）;
 intentApp.addFlags（Intent.FLAG_ACTIVITY_SINGLE_TOP）;
 PendingIntent piApp = PendingIntent.getActivity（此，0，intentApp，0）;

 意图int​​entOnOff =新的意图（CV.SERVICE_INTENT_ACTION）;
 intentOnOff.putExtra（CV.SERVICEACTION，CV.SERVICEACTION_TOGGLE）;
 PendingIntent piOnOff = PendingIntent.getService（此，0，intentOnOff，0）;

 意图int​​entScreenOff =新的意图（CV.SERVICE_INTENT_ACTION）;
 intentScreenOff.putExtra（CV.SERVICEACTION，CV.SERVICEACTION_SCREENOFF）;
 PendingIntent piScreenOff = PendingIntent.getService（此，1，intentScreenOff，0）;

 //设置远程视窗
 RemoteViews remoteViews =新RemoteViews（getPackageName（），R.layout.layout_notification）;
 remoteViews.setOnClickPendingIntent（R.id.image_logo，piApp）;
 remoteViews.setOnClickPendingIntent（R.id.image_status，piOnOff）;
 remoteViews.setOnClickPendingIntent（R.id.image_screenoff，piScreenOff）;

 如果（CV.get prefChargingOn（本）及和放大器; CV.isPlugged（本））
 {
     remoteViews.setImageViewResource（R.id.image_status，R.drawable.widget_charging_on）;
 }
 其他
 {
     如果（CV.get prefAutoOnoff（本））
     remoteViews.setImageViewResource（R.id.image_status，R.drawable.widget_on）;
     其他
     remoteViews.setImageViewResource（R.id.image_status，R.drawable.widget_off）;
 }

 //建立通知
 通知NotI位=新Notification.Builder（本）
 .setContent（remoteViews）
 .setSmallIcon（R.drawable.ic_launcher）
 .setOngoing（真）
 。建立（）;

 回报NotI位;
 

code更新notificaton，接到意向后：

 通知通知= createNotification（）;
 最后NotificationManager notificationManager =（NotificationManager）getApplicationContext（）
                        .getSystemService（getApplicationContext（）NOTIFICATION_SERVICE。）;

 notificationManager.notify（NOTIFICATION_ONGOING通知）;
 

我的问题是：叫我的更新功能后，通知图像实际上是改变;然而，通知面板依然存在!! 它不会消失，就像它应该是什么样的发射活动。

有一个标志，我可以通知，pendingIntent设置，或者是API调用接收意向的售后服务，我可以使用？

解决方案

找到我的问题回答了在其他地方：

首先，添加使用许可行的Andr​​oidManifest.xml

 ＆LT;使用-权限的Andr​​oid：名称=android.permission.EXPAND_STATUS_BAR/＆GT;
 

第二，使用下面的codeS，使其工作：

 尝试
{
    对象服务= getSystemService（状态栏）;
    类＆LT;＆GT; statusbarManager =的Class.forName（android.app.StatusBarManager）;
    如果（Build.VERSION.SDK_INT＆LT; = 16）
    {
        方法塌陷= statusbarManager.getMethod（崩溃）;
        collapse.setAccessible（真正的）;
        collapse.invoke（服务）;
    }
    其他
    {
        方法collapse2 = statusbarManager.getMethod（collapsePanels）;
        collapse2.setAccessible（真正的）;
        collapse2.invoke（服务）;
    }
}赶上（例外前）{}
 

这是哈克，但它确实工作。

I write a service to to update system state, and I use startForeground to put the service to foreground, also adding a notification to it. In the notification, I use remoteView to have three images with three OnClickPendingIntent. One of them is sending back to the service, and do the notification update codes.

code for creating notification:

 Intent intentApp = new Intent(this,ScreenOffWidgetConfigure.class);
 intentApp.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
 PendingIntent piApp = PendingIntent.getActivity(this, 0, intentApp, 0);

 Intent intentOnOff = new Intent(CV.SERVICE_INTENT_ACTION);
 intentOnOff.putExtra(CV.SERVICEACTION, CV.SERVICEACTION_TOGGLE);
 PendingIntent piOnOff = PendingIntent.getService(this, 0, intentOnOff, 0);

 Intent intentScreenOff = new Intent(CV.SERVICE_INTENT_ACTION);
 intentScreenOff.putExtra(CV.SERVICEACTION, CV.SERVICEACTION_SCREENOFF);
 PendingIntent piScreenOff = PendingIntent.getService(this, 1, intentScreenOff, 0);

 // setup remoteview
 RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.layout_notification);
 remoteViews.setOnClickPendingIntent(R.id.image_logo, piApp);
 remoteViews.setOnClickPendingIntent(R.id.image_status, piOnOff);
 remoteViews.setOnClickPendingIntent(R.id.image_screenoff, piScreenOff);

 if(CV.getPrefChargingOn(this) && CV.isPlugged(this))
 {
     remoteViews.setImageViewResource(R.id.image_status,R.drawable.widget_charging_on);
 }
 else
 {
     if(CV.getPrefAutoOnoff(this))
     remoteViews.setImageViewResource(R.id.image_status,R.drawable.widget_on);
     else
     remoteViews.setImageViewResource(R.id.image_status,R.drawable.widget_off);
 }

 // build the notification
 Notification noti = new Notification.Builder(this)
 .setContent(remoteViews)
 .setSmallIcon(R.drawable.ic_launcher)
 .setOngoing(true)
 .build();

 return noti;

code for updating notificaton, after receiving the intent:

 Notification notify = createNotification();
 final NotificationManager notificationManager = (NotificationManager) getApplicationContext()
                        .getSystemService(getApplicationContext().NOTIFICATION_SERVICE);

 notificationManager.notify(NOTIFICATION_ONGOING, notify);

My question is: after calling my updating function, the notification image is actually changed; however, the notification panel is still there!! It does not disappear just like what it should be for launching activities.

Is there a flag I can set for notification, pendingIntent, or what API calls I can use after receiving the intent in service?

解决方案

find my question answered in other place:
1. Android: How to collapse status bar on android 4.2? 2. Preventing status bar expansion

first, add use permission lines to AndroidManifest.xml

<uses-permission android:name="android.permission.EXPAND_STATUS_BAR"/>

second, use following codes to make it work:

try
{
    Object service  = getSystemService("statusbar");
    Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
    if (Build.VERSION.SDK_INT <= 16) 
    {
        Method collapse = statusbarManager.getMethod("collapse");
        collapse.setAccessible(true);
        collapse.invoke(service);
    } 
    else 
    {
        Method collapse2 = statusbarManager.getMethod("collapsePanels");
        collapse2.setAccessible(true);
        collapse2.invoke(service);
    }
}catch(Exception ex){}

it's hacky, but it did work.
